Estimated linear weight.
Explanation
What this calculates
The internal diameter is estimated by deducting twice the wall thickness from the outside diameter.
Formula
Area = outside circle - inside circle; weight = area x density x length
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
